Young, "Demonstration of all-optical CDMA with bipolar codes," vol. 2, 1997.https://hdl.handle.net/1911/19857Conference PaperUsing a fiber-based testbed, we experimentally verify that the advantageous correlation properties of bipolar spread-spectrum codes can be preserved in an optical channel using direct detection and all-optical encoder/decoders. The power spectrum of an erbium-doped superfluorescent fiber source is encoded, the codeword correlations are verified and rejection of multiple-access interference is demonstratedengcode division multiple access (CDMA)bipolar codesall-opticalencoders/decoderserbium-doped superfluorescent fiberConference papercode division multiple access (CDMA)bipolar codesall-opticalencoders/decoderserbium-doped superfluorescent fiberhttp://dx.doi.org/10.1109/LEOS.1997.645160
